Background
The existing cable is generally composed of a conductor and a polyvinyl chloride insulating layer formed on the periphery of the conductor in an extrusion molding mode, and in the using process of the cable, the insulating layer and the flame-retardant layer of the cable are easy to wear so as to damage the insulating performance of the cable, and potential safety hazards exist;
the utility model patent in China with the application number of 201120164737.9 discloses a fire-resistant wear-resistant flame-retardant cable, which comprises a conductor positioned in the center and an insulating layer coated on the periphery of the conductor, wherein the insulating layer sequentially comprises a mica tape wrapping layer, a flame-retardant polyvinyl chloride insulating layer and a nylon protective layer from an inner layer to an outer layer. The mica tape with strong fire resistance is wrapped between the flame-retardant polyvinyl chloride insulating layer and the conductor, and the nylon protective layer with strong wear resistance is wrapped outside the flame-retardant polyvinyl chloride insulating layer, so that the whole insulating layer is not easy to damage in the use process of the whole cable, the cable can keep working normally in case of fire, and the quality of the cable is further improved.
However, the above patent has the following problems: due to the lack of the supporting structure, the overall strength of the cable is insufficient, and the protection requirement cannot be met only by relying on the wear resistance of the nylon layer; meanwhile, the insulating and flame-retardant layers are too single, and the flame retardance and the wear resistance are insufficient.
Disclosure of Invention
The utility model aims to provide a wear-resistant flame-retardant cable, which solves the problems in the background technology.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
